leKpz M 41 90 mm GF

Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value.
These differences are taken into account in tooltip boxes.

Performance

This tank takes some of the best attributes from all the other lights at tier and combines them all to create a very versatile light tank that can load its HEAT shell and go after some of the bigger tanks in the game, or can load up its HEP and chase down other lights, or even load AP and perform a sniping role.

However, this tank does have its limitations as your HEP shell will almost never work against the better armored light tanks. You can also count out any chance of a random bounce here and there, as it has a max of 25mm of armor and if you're fighting anything with good HE rounds you're better off staying side-on and hoping your tracks block their HE shell.

In the end, this tank is a premium vehicle and can more than compete with its non-premium counterparts while making a decent profit as long as you keep from firing too much HEAT.

A viable strategy when using the M41 GF is to initially load your HEP shell and do some aggressive active spotting to farm some initial spots and spotting damage. Then adapt to more of a flanking medium, spotting where needed and working to ensure your team maintains vision and health superiority.

With patch 9.18 the non-premium American M41 Walker Bulldog has been moved up to tier 8, while at the same time having its auto-loading gun nerfed. As a result, the M 41 90 was better in some aspects such as penetration on both standard and premium ammunition and DPM but is severely outclassed in terms of mobility. Additionally, the M41 Walker Bulldog got 2 more degrees of gun depression when using the single-shot guns.

After the series of 9.20 patches, the competing M41 has lost its autoloader altogether. As it stands, DPM, pen, alpha damage, aim time, top speed and total HP are better for M 41 90 while shell velocity, gun handling, gun depression, power-to-weight, mobility and some lesser aspects are better for M41.
